e CUSI-IiONING APPLIANCE FOR LOCOMOTIVES.

Speciflcation of Letters Patent.

Patented Oct. 22, 1907.

Application filed July 22, 1907. Serial No. 385,019.

To all whom it may concern:

Be it known that 1, WILLIAM DALTON, oi Schenectady, in the county of Schenectznlyand State of New York, have invented a certain new and useful lmprovemerit in Cushioning Appliances for Locomotives, of which improvement. the foll wing is a specification.

My invention relates to appliances designed to cushion the side blows of locomotives upon the rails when running at. high speeds, so as to minimize the jars and shocks resultant therefrom, an instance of such appliances being exemplified in LettersPatont of the United States No. 841,379, granted and issued to American Locomotive Company, as my assignee, under date of January 15, .1907.

The object of my present invention is to simplify and economize the appliance of said Letters Patent, while attaining the same usefully operative results.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a horizontnl section through a portion of a locomotive frame, illustrating an application of my invention; Fig. 2, a side view, in elevation, of the same; Figs. 3 and 5, horizontal sections through portions of locon'iotive frames, illustrating structural modifications; and, Figs. 4 and ti, side views. in elevatitm, of the constructions shown in Figs. 3 and 5, respectively.

My invention is herein. as in Letters Patent N 841,378) aforesaid. exemplified as applied in connection with axles, 2, of an electric locomotive, upon which wheels, 4, are secured, and which are journaled in axle boxes, 3, in the ordinary manner. Pairs of vertical lateral flanges, 3 and 3, are formed on the axle boxes, and pedestal shoes, 59, are fitted in the spaces or recesses between said flanges. Each of the shoes; 5*, is provided with vertical lateral flanges extending on opposite sides of one of a pair of vertical pedestal jaws. 5*, fixed on, and constituting part of, on of the side frame members, 5, oi the locomotive, the construction providing for verti al movement of the pedestal jaws and shoes. relatively to the axle boxes, and being. as thus far described, one which is well known in ordinary practice.

In the constructitm set forth in Patent No. 84l,379 aforesaid, the inner side flanges of the pedestal shoes are vertically recessed, and springs, interposed between an d bearing on said flanges and the pedestal jaws, are fitted in the recesses of the pedestal shoes. This specific construction ofparts, while satisfactorily attaining the result for which it. is designed, is subject to the objections that it involves an increase in the trans verse length of the pedestal shoes and prevents ready access to the springs when required' These objections are effectually overcome under my present invention,

in the practice of which the pedestal shoes are not vertically recessed, and may therefore be of ordinary length transversely t0 the longitudinal plane of the locomotive.

The distancebotween the members of each pair of vertical lateral flanges of the pedestal shoes, 5', is greater than the width of the pedestal jaws, so as to leave sufilcient space or clearance to admit; of the lateral movement of the axle boxes and shoes and the c0mpression of the springs which are provided for resisting such lateral movement. The springs, 10, by which resistance to side blows upon the rails is exerted, and by which the shocks and jars due thereto are cushioned, are located entirely exterior to the pedestal shoes, and are so disposed, relatively thereto and to the pedestal jaws,'as to be subjected to compression by longitudinal movements, that is, lateral movements relatively to the locomotive, of the axles and axle boxes in either direction.

Variations in the form and location of the cushioning springs, 10", may be made, in the discretion of those familiar with locomotive construction, without departure from the spirit and essential feature of my invention. As shown in Figs. 1 and 2, said springs are of helical form. and abut against the outer sides of the outer flanges oi the pedestal shoes and against followeis, 10*;which-are adjustable by nuts, 10, on stems, 10, fixed in the pedestal shoes. It will be seen that the springs on the side of the locomotive shown in Figs. 1 and 2 will be compressedby nmvements of the axles and axle boxes in the direction of the arrows, and will be understood that those on the opposite side of the locomotive will be compressed by movements of the axles and axle boxes inahe opposite direction.

Figs. 3 to t) inclusive illustrate the application of similarly operating cushioning springs, ll), of plate form. extending lmtgitudinally 0n the side frame memher, and abutting, at their middle portions, on bcarings, 1.0", fixed to the frame members, and, at their ends, on the adjacent ped stal shoes of two adjacent axles, when located between the axles, or on a pedestal shoe at one end and a frame bearing, 10", at the other, when located longitudinally beyond the axles. -The springs of Figs. 3 and 4 bear on the pedestal shoes on the inner sides of the pedestal jaws, 5 and'those of Figs. 5 and 0 on the outer sides of said jaws. The 10 springs are compressed, and their resistance to side blows exerted, by the lateral movementsof the axles audaxlc boxes, in the same manner, and with the same effect, as in the instance firstdescribed.

My present invention provides means for attaining the same beneficial result of cushioning and minimizing the injurious effect of side lurchiiig or abrupt lateral movement of locomotives when running at high speeds I claim as my invention and desire to secure by Let ters Patent:

- 1. The combination of a locomotive-axle, 'nxlbFboXesl-n which said axle ls jonrnaled. side frame members in whiflh the axle boxes are fitted and whichwith the :rxh. are capable of lateral movement relatively to the side frame members, pedestal shoes engaging-rind movable laterally with the axle boxes. and cushioning springs disposed exteriorly to the pedestal shoes and hearing theroon and on the side frame members. v i

2. The combination of a locomotive axle, axle boxes in which said axle is journalod. side'frame member pedestal jaws located on opposite sides of the axle boxes, shoes fitting in lateral recesses on the axle boxes and having lab oral (hinges extending on opposite sides of the pedestal jaws and providing space or clearance for lateral movement, and cushioning springs disposed exteriorly to the shoes and compressible between said shoes and the side ,ililllli} lllllllblllS, in and by lateral traverse of the axle .boxos. I

.l. The (rombination' of a locomblivu axle. axle boxes in which d llXlQ is .io ll n ed, side frame members in which $.th'e hil -Moms are. littednnd which, with the axle. 9.1 9

4. 'lhv combination of a locomotive axle. axle boxes in \vhioh'si i'll iixle is journalod, side frz lme member pedestal jaws l C;llL(l on opposite sides of the axle boxes. shoes lilting in lateral recesses in the axle boxes and having lateral flanges extending on opposite sides of the pedestal jaws and providing space or clearance for lateral movement of the axle. and plate springs extending longitudinally between hearings on the side frame members and on the shoesv \VILLIA DALTON.
